Dispensing valve for a sealed pressurized container

ABSTRACT

A dispensing valve carried by a connector adapted to clamp upon the bezel of the container so as to center the valve thereon and to pierce and seal the closed top of the container. The valve comprises a valve head, a penetrating dispensing tube and a seal. When the valve is clamped on to the bezel of the container the valve head is threaded through the clamping connector causing the seal to contact the top of the container at the point of penetration thereof by the dispensing tube. The valve and the connector can be removed and reused when the contents of the pressurized container have been dispensed.

DISPENSING VALVE FOR A SEALED PRESSURIZED CONTAINER SUMMARY OF THE INVENTION A removable, reusable dispensing valve for a sealed pressurized container including a clamp for connecting the valve to the bezel of the container and for centering the same relative to the closed top thereof. The valve comprises a body member threadable through the clamp after the same has been attached to the container with the body member carrying therewith an exposed end of a penetrating tube which in turn is surrounded by a compression seal. As thebody member is threaded relative to the clamp and into the direction of the closed top of the container the penetrating tube will pierce the top of the container and its surrounding compression seal will seal such opening to prevent the pressurized contents of the container from escaping except through the dispensing valve.

FIG. 7 is a sectional view of the valve body of the dispensing valve taken on line 7-7 of FIG. 6.

The principal object of the dispensing valve 10 is to provide a quick, safe and positive attachment of the valve to a sealed pressurized container and to provide automatic valving of the contents thereof.

The valve 10 includes a clamp structure 11 which comprises two disclike members 12 and 13. Each of the disclike members l2 and 13 is provided with a center opening 14 and 15 with the opening 15 in the disc member 12 defined by a protruding rim 16 which is internally threaded as at 17.

Each of the disclike members 12 and 13 of the clamp 11 provide radially extending flanges l8 and 19 which are fonned into a substantially U-shaped clamp 20 and 21, having their free edges arcuated as at 22.

The disclike member 13 provides a second radially extending flange 23 which terminates into an elongated handle 24. The flange 23 provides on its undersurface a depending pin 25 that is adapted to be disposed into a sector 26 removed from the peripheral edge of the disclike member 12 as seen in FIG. 6. The pin 25 in its movement through the removed sector 26 determines the amount of rotational movement between the disclike members 12 and 13.

When, as shown in FIG. 2, the depending pin 25 is at one end of the removed sector 26 the radially extending flanges l8 and 19 of each of the disc members 12 and 13, as well as their U-shaped clamps 20 and 21, are disposed angularly with respect to each other such that the bezel 27 of the container 28 may be disposed upon the arcuated edges 22 thereof, and through the utilization of the handle 24 the disc member 13 it may be pivoted relative to the long axis of the container such that the arcuated edges 22 are disposed diametrically with respect to each other in the manner seen in FIGS. 4 and 5 so as to connect the clamp structure 11 to the bezel 27 of the container 28.

As seen in FIGS. 4 and 5 the disclike members 12 and 13 have been placed in facial abutment with the protruding rim 16 of the member 12 inserted into the center opening 14 formed in the disc member 13. The valve body 29 provides an externally threaded stud portion 30 which is adapted to be threaded into the rim 16 in the manner shown in FIG. 4.

The threaded stud portion 30 of the valve body 29 encircles a bore 31 which internally terminates into a reduced counter bore 32 that through an open passage 33 has open communication with a discharge port 34.

Positioned within the discharge port 34 of the valve body 29 is a hose connection core 35. This core 35 contains a valve stem 36 which is of a construction well known in the art and makes up no part of the present invention except as a cooperative component for the entire structure.

Adapted to be placed within the counter bore 32 provided in the valve body 29 is an elongated metallic penetrating tube 37. This tube 37 is adapted to be encased in a seal 38 which in turn is positioned within the open bore 31 formed in the one end of the valve body 29. The latter parts are so arranged that the penetrating tube 37 provides an exposed penetrating point 39 that extends beyond the exposed extremity of the seal 38 such as is shown in FIGS. 4 and 5.

When this clamp structure 11 has been mounted and fixedly attached on to the bezel 27 of the pressurized container 28, the valve body 29 is threaded through the rim 16 until the exposed tip 39 of the penetrating tube 37 forcibly pierces the top wall 40 of the sealed container 28 such as is shown in FIG. 5. When the exposed tip 39 of the penetrating tube 37 pierces the top wall 40 of the container 28, the seal 38 surrounding such tip 39 is compressed into abutting relation with the top wall 40 so as to seal the opening formed therein by the tip 39.

When the valve is thus mounted to a pressurized sealed con tainer the content of such container, being contained therein under pressure, is free to move through the penetrating tube 37, the passage 33 and into the exhaust port 34 and core 35 and against the valve stem 36. When a hose (not shown) is connected to the core 35 a valve depressor carried thereby will longitudinally move the valve stem 36 in the core 35 permitting the pressurized contents of the container to be valved therethrough.

When the container has been emptied the dispensing valve may be removed from the container by the reverse threading of the valve body relative to the clamp structure 11 and the pivotal movement of the disclike members 12 and 13 relative to each other, such that the entire structure may be readily removed from the bezel 27 of the container 28.

Under the present invention the valving of the contents of the container is automatic such that it is actuated by attaching the dispensing hose thereto. This speeds the process of dispensing the contents, and offers a highly desirable feature, which is a safety factor, in that the valve cannot be inadvertently left open or accidentally opened, thus resulting in the loss of the contents of the container.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and'modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
